We formulate a variant of the “double Monod model” which takes explicit account of endogenous metabolism. Using parameter values appropriate to carbohydrate‐limited substrate, bacterial prey, and protozoan predator, we study the stability of steady states under chemostat conditions. We conclude that the predator's endogenous metabolism may have a stabilizing effect at low dilution rates.
